Acoustic Metamaterial Superenhances Sound Detection Limits By More Than 10 Fold

by on October 24, 2014
Metamaterials are composite materials with exacting, repetitive subwavelength structural patterns that have properties not found in nature.  Thus far, they have been used to create novel optical materials with negative index of refraction, thus permitting “superlenses” that have enhanced optical resolution beyond conventional lenses, and “invisibility cloaks” that bend at least a narrow band of […]

Iridescence Camouflages A Lizard’s Head Against Overhead Predator But Increases Visibility To Co-Level Mates

by on October 23, 2014
The phenomenon of iridescence is caused by microscopic regularities on the surface that scatter light in an angle-dependent fashion.  Scientists from Valencia University have discovered that not only are the heads of the Iberian emerald lizard iridescent, but the lizard seems to exploit the angle dependence by being innocuous when viewed above as from the […]


Human Skin Contains An Odor Receptor That Responds To Sandalwood Smells By Enhanced Healing

by on October 23, 2014
The skin is an important major organ, the function of which includes acting as a protective covering against injury for underlying tissue, as well as a sensing, cooling, and water retention among others.  Now German researchers have discovered that there is an odor receptor expressed in at least keratinocytes, a major skin cell type, and that […]

Noncovalent, Self-Assembled, Robust, Porous Material That Adsorbs Greenhouse Gas

by on October 22, 2014
Researchers from the Department of Chemistry at the University of Houston have created noncovalent organic frameworks, a new type of porous material that overcomes some barriers in the development of porous material technologies.  The new wonder material is highly processable, self-assembled, possessing of a superstructure with large, 16 angstrom pores (Figure above).  The material has a […]


Dark Matter X-Ray Signature From Beyond The Standard Model Revealed By Space Observatory

by on October 21, 2014
Astronomers analyzing 12 years worth of X-ray data from the European Space Agency Multi Mirror Mission (XMM-Newton) have found excess detected emissions comparing between two locations around the Earth.  In one location, at the Sun-side, more emissions were detected versus in the other location, at the far side.  Ruling out known sources of X-rays such […]

Gut Bacteria Found To Be Causal Factor In Weight Gain

by on October 19, 2014
Metagenomic sequencing of gut microbiota in previous studies have shown over-representation of Clostridium bacteria species in people with Type 2 diabetes, and obese adults (the studies were performed by Swedish scientists led by Fredrik Backhed and a consortium including MetaHIT, both published in Nature, see references below). Now a research team from the German Institute […]

Robotically-Controlled Swimming Nanomotors Carve Out Next-Generation Nanoscale Computer Chip Lithographic Features

by on October 17, 2014
University of California San Diego researchers have imagined and realized a low cost, innovative solution to next-generation nanofabrication that could be applied to advanced computer chip creation using tiny nanomotors inspired by biology.  The researchers showed that it is possible to carve out well-defined, nanoscale features such as ridges and trenches in a substrate, basic components […]


New Omnidirectional Broadband 2D Crystal Efficiently Absorbs 85% Of Photon Energy

by on October 16, 2014
Research engineers at MIT have developed a novel solar material in the form of a 2D metallic, dielectric photonic crystal.  The material has remarkable properties of broadband absorption of sunlight, from visible to near infrared portions of the spectrum, with little dependence on the angle of the incident light.  Efficiencies in these bands were measured to […]

Children Born Soon After The Great 1998 North American Ice Storm Show DNA Imprint 13 Years Later

by on October 15, 2014
Researchers have discovered that maternal stresses effect changes in the DNA of the offspring in long term ways.  In a study of expectant mothers in the 1998 North American Ice Storm and their children 13 years later, the researchers found that the number of days the expectant mother was deprived of electricity was predictive of […]
